On your wedding day you leave for the church 28 minutes before the ceremony is to begin, which should be plenty of time since the church is only 10.0 miles away. On the way, however, you have to make an unanticipated stop for construction work on the road. As a result, your average speed for the first 14 minutes is only 5.0 mi/h. What average speed do you need for the rest of the trip to get you to the church on time?

It’s your wedding day and the distance from your house to the church is 10km and your wedding starts at 8:00 AM. If you ride a car (w/ an average velocity of 5m/s) starting at your house at 7:45AM, will you be late for your wedding?
